I have a 2002 yz426f and I left it in my house for 3 days and when I went to start it it would not start do any of you have any ideas why it wont start

Don't you think some information would be helpful. Can you work on it. Does it have gas, spark, clean filter, compression, how many hours, and checked the valves.

Yes I can work on it. It has gas,compression,filter is a little dirty. It ran good 4 days ago. I just took off all the finders and stuff to clean them and when I put them back on the bike would not start. :bang:

Clean the air filter. Check the valves. And stop beating your head against the wall, it will not help, usually.

does it have spark????
if all you did was remove fenders to clean maybee you knocked a wire loose??????

Yes it has spark I took off the boot and put a new spark plug in to see if is had spark. But I cant replace the plug because I dont have a plug tool I have to go get one. The plug is down in the head

i had an old rm that wouldnt start because the wire that went to the top of the plug wasnt connected very well andit wasnt gicing it proper spark

unplugged a wire somehow, ground wire grounding out, compression not as good as you think, gas tank empty/not enough, petcok off, valves tight, rag in air intake, all things ive seen happen.
